EXTENSION-TAB LE.

SPECIFICATION forming part of Letters Patent No. 667,387, dated February5, 1901.

Application filed September 22, 1900. Serial No. 30,833. (No model.)

To all whmn it may concern:

Be it known that I, WILLIAM E. DEPP, a citizen of the UnitedStates,residing at Brookville, in the county of J elferson and State ofPennsylvania, have invented a new and useful Extension-Table, of whichthe following is a specification.

My present invention relates to improvements in extension-tables of thatclass which comprehend the table proper and collapsible extensionsdesigned to be collapsed and slid into the table-body or withdrawntherefrom and reorganized for the purpose of constituting extensions theupper and side surfaces ofwhich are flush with the upper and sidesurfaces of the table.

The object of the invention is to provide a simple and durableconstruction for rendering the extensions readily collapsible orexpansible to facilitate their storage within the table-body or theiraccurate positioning when it is desired to extend the table.

To the accomplishment of this object and others subordinate thereto, aswill hereinafter more fully appear, the invention is comprehended in thepreferred form thereof illustrated in the accompanying drawings andsuccinctly defined in the appended claims.

In said drawings, Figure 1 is a perspective of my table, showing one ofthe extensions positioned with its surfaces flush with thetable-surfaces, the other extension being collapsed and ready forfurther Withdrawal from or inclosure within the table. Fig. 2 is acentral longitudinal section through the table, showing one of theextensions inclosed therein and the other drawn out as in use. Fig. 3 isa transverse section on the line 3 3 of Fig. 2. Fig. 4 is a bottom planview of the table with the parts in the positions shown in Fig. 2. Fig.5 is a fragmentary sectional view on the line 5 5 of Fig. 2, and Fig. 6is a similar view on the line 6 6 of Fig. 2.

Referring to the numerals of reference employed to designatecorresponding parts in the several views, 1 indicates a table, and 2 and3 the table extensions or extensible sections designed, in a manner tobe described, to he slid into the table or to be withdrawn therefromwhen it is desired to extend the supporting-surface of the table by theaddition of one or both of the extensions. The

table 1 comprises a body portion composed of a horizontal top 4,permanent side rails 5, depending from the opposite edges of the top, aseries of base-bars 6, extending transversely between the lower edges ofthe side rails 5, and a suitable supportas, for instance, a leg-frame7comprising a number of connected legs, upon the upper ends of which thebase-bars 6 are retained in any suitable manner. The table as thusconstructed comprehends a suitably-supported open-ended box-likereceptacle within which the extensions 2 and 3 are designed to be storedwhen not in use. For the purpose of properly guiding the movements ofthe extensions or extensible sections 2 and 3 the table is provided witha pair of parallel sliderails 8, having longitudinal grooves 9 in theirside faces for the reception of correspondingly-formed tongues 9 formedupon the faces of the slides 10 and 11, extending in opposite directionsfrom the extensions.

As shown more clearly in Fig. 4 of the drawings, each of the extensionsis provided with a pair of slides, the slides 10 comprising supports forthe extensions 2 and engaging the outer faces of the guide-rails 8, andthe guides 11 serving a like purpose for the extension 3 and engagingthe inner faces of the rails. By this arrangement it will be seen thatthe slides are arranged out of coincidence to permit them to moveindependently in order that either one or both of the extensions may beemployed, as desired, for the purpose of extending thesupporting-surface of the table.

In addition to the slides each of the extensions comprehends an end rail12, from which the slides extend, an extension leaf or top 13, and thefolding side rails or side-rail extensions 14. The end and side rails ofthe extensions conform in design and transverse dimensions to thosecharacteristics of the permanent side rails of the table, so that whenthe extensions are drawn out the leaves 13 will constitute extensions ofthe table-top, and the side and end rails 14 and 12 will constitutecontinnations of the side rails of the table to impart a finishedappearance to the latter.

Obviously the supporting-surfaces of the table and the extensions andthe outer surfaces of the side rails and their extensions must lieflush, which necessitates the abutting of their contiguous ends, and ittherefore follows that some special provision for effecting the partialcollapse of the extensions must be made in order that they maybe slidinto the box-like body of the table when the extended form of the tableis not desired. It is in this provision that the most important featuresof my invention are embodied.

By reference to Figs. 2, 3, 5, and 6 of the drawings it will be notedthat the upper edges of the slides are located a considerable distancebelow the upper edges of the end rails 12, which latter are located inthe horizontal plane of the supporting-surface of the table.

The purpose of this is to permit the end rails to completely close theends of the table when the extensions are moved in and to provide fordropping or depressing the leaves 13 to a horizontal plane below theplane of the tabletop 4 to permit them to slide under the top, as shownin Figs. 1 and 2 of the drawings. It is essential, however, that theseleaves be securely retained in their elevated positions when theextensions are used; but it is quite as essential that they may bereadily depressed or dropped when necessary. To obtain these results, Iprovide each leaf 13 with a pair of depending leaf-supporting plates 15,opposed to the outer faces of each of the slides 10 or the inner facesof the slides 11, as the case may be. Each of these supporting-plates isprovided with an angular slot 16, through which extends a projection,pin, or stud 17 upon the side wall of the adjacent slide. The horizontalbranches 16 of these slots are located adjacent to the lower ends of theplates, and their vertical branches 16 are located adjacent to the outeredges of the plates, as shown more clearly in Fig. 2. of the drawings.

It will now be seen that if the pin or projection 17 is located in thehorizontal branch 16 of the slot the leaf will be supported in itselevated position with its upper surface flush with thesupporting-surface of the table. If, however, the leaf is shifted topresent the vertical branch 16 of the slot above the pin, the leaf willdrop upon the slides and will be located in a plane below the plane ofthe table-top 4 to permit the extension to slide into the table, asshown at the right of Figs. 2 and 4. Similar provision for the collapseor folding of the side rails 14 of the extensions must be made; but asthe opposite ends of the leaves 13 abut against the inner faces of thepermanent side rails 5 it will appear that the movable side rails cannotbe shifted laterally out of the plane of the rails 5, but must be turnedunder the leaves 13 and slid inwardly to prevent their protrusion beyondthe ends thereof. The peculiar form of mounting which I employ toaccomplish this'end is'best shown in Figs. 4, 5, and 6 of the drawings,wherein it will be seen that each of the movable side rails 14 isconnected to its leaf 13 by one or more leaf-hinges 18, each having a.the pins 22 from the sockets 21.

leaf 18 permanently connected to the inner face of the side rail and aleaf 18 shiftably mounted upon the under face of the extension-leaf 13by providing the hinge-leaf 18 with an elongated opening or slot 19,engaged by a stud 20, extending from the extensionleaf 13. r

The extension side rails 14 are not only employed to impart a finishedappearance to the table, but are intended to constitute additionalsecuring or supporting means for holding the leaves 13 in their elevatedpositions. I therefore provide each rail 14 with a recess or socket 21inits inner end edge for the reception of a pin 22, projecting from theadjacent end of one of the permanent side rails 4, and at the oppositeend of the rail 14 I provide a pin 23, designed to engage a recess orsocket 24 in the face of the adjacent end rail 12, this particularrelation of the pins and sockets being desirable, as it permits the pins22, carried by the permanent side rails, to enter the sockets 24 of theend rails when the extensions are slid into the table.

The manipulation of the table constructed in accordance with myinvention is as follows: Assuming the table to be organized asillustrated in Fig. 1 of the drawings, and that it is desired todiscontinue the use of the extensions, the end rail 12 of the extension3 is drawn back to effect the disengagement of The leaf 13 is then movedaway from the end rail for the purpose of withdrawing the pins 23 fromthe sockets 24 and to cause the vertical branches 1t of the slots 16 tobe presented above the pins 17. The result of this reorganization willbe to permit the leaf to drop upon the upper faces of the slides and ina plane below that of the top 4, as shown in Figs. 3 and 6 of thedrawings. The end rails 14 of the extension are now swung under the leaf13, as shown in dotted lines in Fig. 5, and their projecting edges aremoved within the ends of the leaf by sliding the rails under the latterto the positions indicated in Fig. 6 of the drawings, after which theextension may be readily slid into the table, as shown at the right ofFigs. 2 and 4. When it is desired to extend the table, it is simplynecessary to draw out the slide and effect the reversal of themanipulation of parts just described.

From the foregoing it will appear that I have produced a simple,durable, and easilymanipulated extension-table embodying a constructionadapted for the accomplishment supported by the slide and capable ofassuming positions in different horizontal planes, leaf-hinges slidablymounted upon the under side of the leaf adjacentto its ends, andfoldable side-rail extensions connected to the leaf by said hinges anddesigned to be swung to a position below the leaf and to he slid bodilythereunder.

2. The combination with a table comprising a top, pendent side railspermanently connected to the top, and slide-rails located below the top,of an extension comprising an end rail, slides extending therefrom andslidably engaging the slide-rail of the table, an extension-leafsupported by the slide and provided with pendent plates having. angularslots, pins extending from the slides through the slots of said platesto permit the leaf to be supported in the plane of the table-top or in aplane therebelow, a pair of foldable siderail extensions located at theopposite ends of the extension-leaf, hinges connecting said railextensions to the leaf, each of said hinges being provided with alongitudinal slot, a pin projecting from the under face of the leaf andengaging the slot, means for effecting an interlocking engagementbetween the rail extensions and the permanent side rails, and means forefiecting a similar engagement between the rail extensions and the endrail.

3. The combination with a table comprising a top and side rails, of anextension comprising a slide, an extension-leaf supported by the slideand capable of assuming positions in difierent horizontal planes, a pairof foldable side-rail extensions located at the opposite ends of theextension-leaf, hinges connecting said rail extensions to the leaf, eachof said hinges being provided with a lon= gitudinal slot, and a pinprojecting from the leaf and engaging the slot, whereby the siderailextensions may be swung to a position below the leaf and slid bodilythereunder.

4:. The combination with a table comprising a top and side rails, of anextension comprising a slide, an end rail secured to the slide and anextension-leaf capable of assuming positions in different horizontalplanes, a pair of foldable side-rail extensions located at oppositesides of the extension-leaf, leaf-hinges slidably mounted on said leafand hingedly supporting the side-rail extensions to permit the latter tobe swung below the leaf and slid thereunder, means for effecting aninterlocking engagement between the'rail extensions and the rails, andmeans for effecting a similar engagement between the rail extensions andthe end rail.

In testimony that I claim the foregoing as my own I have hereto affixedmy signature in the presence of two witnesses.
